Question

Due to 10% increase in railway fare, the number of passengers in reduced by 10%. Find the percentage increase or decrease in income.
​

Answer 1

Answer:

1% decrease

Step-by-step explanation:

1. Lets assume the fare to be 100 and consumer to be 100
2. so income here is 100×100=10000
3. if 10% fare is increased then fare would be 110 and 10% less consumer would be 90
4. so income here is 110×90=9900
5. so 10000-9900=100 so out of this we get that they loss 100 RS in their total earning which was 10000
6. so 100÷10000×100 is 1%
